Gnar's ultimate - What if it could save you?

I am a Gnar main, and have just reached rank 6 with him. Yay~ But anyways, I notice a lot in team fights when I am slamming people into terrain just how useful my ult could be if it could affect my team mates. I also play Gnar as a support which is honestly how I got my S ranks for mastery lvl 6. I feel it would be a nice tweak to Gnar if he could hurl teammates a set distance. The enemy will still stop on terrain but allies can fly through it if the wall is short enough. This way I could save my adc and stun the enemy at the same time.

The reason I suggest this change is because I've learned that Mega Gnar is good for two things: Tanking and CC. But if your adc is wounded and you jump in to ult, you will stun the enemy for a second or two, then your adc will die because they cannot kill the enemy before they die, since they are lower on hp anyways. Basically Gnar will always lose this situation. The adc will either die, or run away. If they run, the enemy will target Gnar and kill him when he shrinks. If adc stays, she will do a bit of damage before dying before Gnar who lacks consistent damage.

However,if Gnar could stun the enemy while simultaneously tossing the adc, and any other low hp allies, over the wall to safety before jumping over himself... eh?

I feel this wouldn't be broken or unfair because not every wall is one that can be traversed. It would take good positioning of Gnar and his team to be able to use this technique. I am fine with any criticism, and I am not yelling or demanding anything. Just a suggestion to Riot.
